I'm building a new rig to replace my old (8 Years).

This is what i plan to build:

CPU: Core2Duo - E8500
MOBO: Asus Rampage Formula - X48
RAM: Corsair Dominator 4 GB ( 2 x 2 GB ) DDR2-1066 (5-5-5-15)
HD: (Raid-0) 2 x 750GB SATA II
OS: Windows XP Pro 32 Bit
Media: Samsung SH-S203P/BEBN
Case: Antec P182 SE
PSU: Corsair HX620W
Video Card: GeForce 8800GTS 512MB
CPU Cooler: Thermalright Ultra-120 eXtreme with 2x Noctua NH-U12P in Push-Pull config
Soundcard: Creative SoundBlaster X-Fi XtremeGamer Fatal1ty Professional
24" Dell ULTRASHARP 2408WFP

I want to run two 750GB Sata-2 drives in Raid-0 for higher performance NOT as a backup solution (Will backup to external HDD and DVD)

This is so i can run the OS and Apps on the high performance drives and save my data to a slower Big Dumb Disk "BDD" :)

I'm torn between Western Digital and Seagate! They both offer a special "Enterprise" or "Raid Edition" version of their 750GB drives which i have decided to go after since reliability and performance are my primary goals. I know this is not the most cost effective drives from a cost/GB perspective but i'm willing to pay more for reliability.

The choice is between:

[L=Seagate Barracuda ES.2 - 750GB SATA-2 32MB 7200RPM (ST3750330NS)]http://www.seagate.com/ww/v/index.jsp?locale=en-US&name=barracuda-es-2-sata-3-0-gb/s-750-gb-hard-drive-st3750330ns&vgnextoid=52cfc27bebb43110VgnVCM100000f5ee0a0aRCRD&vgnextchannel=b655f141e7f43110VgnVCM100000f5ee0a0aRCRD&reqPage=Model[/L]

[L=Western Digital RE2 - 750GB SATA-2 16MB 7200RPM (WD7500AYYS)]http://www.wdc.com/en/products/products.asp?driveid=335&language=en[/L]

Which has the best performance? Lowest Noise level?

I realise that both drives are of high quality and they both run silent, this makes it so hard to pick a winner!
My primary need when it comes to HDDs is reliability, high performance and silence... In that order.

I appreciate your feedback on this :)

 im a western digital fan so i would say western digital so i would go with them but really they are both good choices with long life and good quilty and you would probably be impressed with either one

I'm using WD RE2 drives in all of my servers these days.  Very reliable.
